“…The majority of the studies used MRI7–17 19–21 23 24 or radiography7 18 21–23 25–29 for measurement of bone morphology parameters. Additionally, Vrooijink et al 12 compared their measurements performed by MRI or intraoperatively, which did not find any correlation. Most of the studies were retrospective case–control studies and their methods are described in table 2.…”

“…The scientific literature describes many predisposing factors for ACL injury, including biomechanical, functional, anatomical and morphological factors. The bony anatomical and morphological parameters described in the scientific literature focus primarily on the femoral intercondylar notch (ICN) and femoral condyles’ shape and dimensions,7–20 notch width index (NWI)8–10 12 14 18 19 21–23 and tibial slopes 8 17 19 21 22 24–29. The pathological association between the ICN and the ACL was first described by Palmer,30 in 1938, when he noticed, as the knee was flexed and supinated, that the ACL was placed in a vulnerable position by being stretched over the inner margin of the lateral femoral condyle.…”

Background Animal models have long been considered an important modality for studying ACL injuries. However, to our knowledge, the value of these preclinical models to study sex-related phenomena associated with ACL injury and recovery has not been evaluated. Questions/purposesWe asked whether (1) prominent anatomic and (2) biomechanical factors differ between female and male porcine knees, particularly those known to increase the risk of ACL injury. Methods Eighteen intact minipig knees (nine males, nine females) underwent MRI to determine the femoral bicondylar width, intercondylar notch size (width, area and index), medial and lateral tibial slope, ACL size (length, cross-sectional area, and volume), and medial compartment tibiofemoral cartilage thickness. AP knee laxity at 30°, 60°, and 90°flexion and ACL tensile structural properties were measured using custom-designed loading fixtures in a universal tensile testing apparatus. Comparisons between males and females were performed for all anatomic and biomechanical measures. The findings then were compared with published data from human knees. Results Female pigs had smaller bicondylar widths (2.9 mm, ratio = 0.93, effect size = À1.5) and intercondylar notches (width: 2.0 mm, ratio = 0.79, effect size = À2.8; area: 30.8 mm 2 , ratio = 0.76, effect size = 2.1; index: 0.4, ratio = 0.84, effect size = À2.0), steeper lateral tibial slope (4.3°, ratio = 1.13, effect size = 1.1), smaller ACL (length: 2.7 mm, ratio = 0.91, effect size = 1.1; area: 6.8 mm 2 , ratio = 0.74, effect size = À1.5; volume: 266.2 mm 3 , ratio = 0.68, effect size = À1.5), thinner medial femoral cartilage (0.4 mm, ratio = 0.8, effect size = À1.1), lower ACL yield load (275 N, ratio = 0.81, effect size = À1.1), and greater AP knee laxity at 30°( 0.7 mm, ratio = 1.32, effect size = 1.1) and 90°(0.5 mm, ratio = 1.24, effect size = 1

“…Studies have also shown that women have smaller notch sizes than men. This may lead to the assumption that the smaller notch possibly contributes to a higher frequency of ACL ruptures in women [14][15][16][17][18][19] . Lombardo et al [20] described that there is no differences between ACL-injured and non-injured basketball players with respect to Notch width.…”

Purpose: The objective of this study was to evaluate multiple morphological features on MR images in patients with ACL insufficient knees. Methods: Magnetic resonance imaging (MRI) of the knee of 40 anterior cruciate ligament insufficient patients and 20 anterior cruciate ligament intact patients who came to Katuri Medical College and Hospital, Guntur, between May 2017 and April 2018 were reviewed. Their intercondylar notch, femoral condyles dimensions and tibial slopes were measured using MRI. Results: The ACL insufficient knees and ACL intact knees were comparable in terms of intercondylar notch width. Lateral femoral condyle height and transepicondylar axis are more in ACL insufficient knees. Medial posterior tibial slope is more than Lateral posterior tibial slope in both ACL insufficient knees and ACL intact knees. Conclusion:The ACL insufficient patients have more Lateral femoral condyle width, intercondylar notch width, intercondylar notch height compared to ACL intact knees. ACL-ruptured patients had statistically significant smaller heights of femur's lateral condyle. MTS is more than LTS in both ACL insufficiency patients and ACL intact patients.Keywords: Magnetic resonance imaging, anthropometric study, knee joint, anterior cruciate ligament IntroductionThe dimensions of the intercondylar notch are such that there is little space not filled by the cruciate ligaments. It is this intimate relationship between the cruciate ligaments and the notch that may give rise to impingement of these structures following anterior cruciate ligament (ACL) reconstruction. Impingement of the ACL on the inter condylar notch will occur if the notch is steno tic, the ACL is relatively large, or a combination of both. This impingement will jeopardize the surgical repair. Magnetic resonance imaging (MRI) has been proven as the gold standard method of choice for non-invasive evaluation of the ACL. Multiple studies have been executed in which measurements were taken on MR images to identify the characteristics of the ACL and its surroundings [1, 2] . Furthermore, MRI has been utilized during the evaluation of knee kinematics with and without an ACL rupture [3,4] . To the best of the authors' knowledge, an assessment of multiple morphological features and their risk for ACL rupture has not been performed. Some studies have investigated the morphological features on the femoral side, while others have studied those on the tibial side. As such, the objective of this study was to evaluate multiple morphological features on both the femoral and tibial sides of the knee on MR imaging in patients with and without ACL rupture. In this way, it is possible to analyze the tibial and femoral morphological features both separately and combined and to evaluate a possible morphological relationship. The hypothesis of this study was that multiple individual and combined morphological features that confer a higher risk of sustaining an ACL rupture could be identified. This complete assessment of multiple morphological features and the...
